Membrane Installation
1
Remove the 1/4" tubing from the membrane housing cap by pressing the collet on the elbow fitting toward the fitting
When the collet is flush with the fitting, the tubing will pull out of the fitting with little effort. Use the aforementioned procedure for removing quick connect fittings.
2
Grip the membrane housing with two hands and remove the membrane housing cap by turning it counterclockwise
3
Remove the membrane from the protective packaging and install it in the membrane housing
There are two O-rings on one end of the membrane. Lightly lubricate these O-rings with the supplied silicone grease.
4
Be sure the membrane is fully seated in the housing
If the membrane is fully seated, it will be about 1/8" - 1/4" inset from being flush with the housing.
5
Lubricate the O-ring on the membrane housing and install the cap hand tight
Tighten the cap an additional 1/8 - 1/4 turn.
6
Push the 1/4" tubing back into the elbow fitting
Be sure it is fully seated in the fitting or a leak could occur. It should not be able to be pulled out with a light tug.
